The TCC solenoid valve is located on the transmission case, typically near the oil pan. It is usually a small, cylindrical-shaped component with a single electrical connector.
Effects of unplugging:
Unplugging the TCC solenoid valve will prevent the transmission from shifting into overdrive, which can result in reduced fuel efficiency and performance. Additionally, it may also cause the transmission to overheat, which can lead to serious damage.
Therefore, it is generally not recommended to unplug the TCC solenoid valve unless you are experiencing specific transmission problems and have consulted with a qualified mechanic.
